MMI not turning on when car starts?

[GregorS]

HI all, sorry if this question has been asked before but could not find it in previous forums. 

My dad has a 2.0 TDi 2016 (66 plate)  the past few weeks now whenever he starts the car (either if engine is cold or warm) the MMI system will not come on, regardless if he presses the on button on the dash. The only way so far he has managed to fix it is pull out the relevant fuse in the boot. He mentioned this to Audi yesterday as it was going in for its MOT. They had a look (not sure what that intales) and they could find nothing, their next steps was for them to look at wiring if he was to give it back to them.

The car has less than 30K on the clock, does about 30 miles a week. Car has never had a problem until now. The MMI is also as upto date has it can be.

 

Any suggestions or ideas? I know this problem can be aimed at any of the Audi range.

 

Thanks for reading and helping!
